TSPNOV2015-2: Images of Bauhinia blakeana ( Fabaceae ) : 1 post by 1 author. Attachments (4)

It is my pleasure to share few images of Bauhinia blakeana (Fabaceae)
Habit: Medium sized tree.
Habitat: Cultivated.
Sighting: Chikmagalur, Karnataka, about 1000 msl
Date: 6-07-2014 and 26-09-2015


Here is a Bauhinia shown by … in Pune. Kindly do the ID.


most probably Hong Kong Orchid tree .. Bauhinia x blakeana, also known as Blake’s bauhinia … please wait for comment(s).


yes B.blakeana from me too.


… attempting to put some visual differences, they too may need validation !!

Blake’s bauhinia has large leaves compared to B. variegata or B. purpurea … PLUS richer in green colour, with a shine.
All the petals have striking pink colour, the central large petal being the most dark of all.
The veins on petals are brighter (white-added), contrary to darker veins in the other bauhinias … my own thought.
Colour of B. variegata ranges from white to purple.
Please wait for easier difference(s).


I am adding my pics of B blakeana in the hope that they will aid comparison. (However I do not notice any shine in the leaves.)

The flowers are very fragrant and a lovely sight.


Many thanks … for validating … agreed there is no shine on the leaves.


That would be my first guess as well. If any seed pods present, then no, as it is a sterile hybrid.


This looks like B. purpurea to me.


Perhaps this should help
B. blakeana                                                    B. purpurea                                       B. variegata
Early flowering, Nov-Dec. in Delhi                      Early flowering Oct-Nov. in Delhi         Late flowering, Feb-March in Delhi
Leaves 15-20 cm across, cleft 14-1/3                 Leaves 10-15 cm across, cleft 1/2      Leaves 10-15 cm across, cleft 1/3
Fls. in long racemes                                         Fls. in short racemes                        Fls. in short racemes
Flowers 12-15 cm across, appear with leaves     Flowers 10-12 cm across, with leaves  Flowers 10-12 cm across, after leaves fall
Petals broad, overlapping,                                 Petals narrow, non-overlapping            Petals broad, overlapping
Petals rose-purple, veins whitish                        Petals pink, whitish in centre              Petals white with purplish veins, upper darker
Stamens 5                                                      Stamens 3                                         Stamens 5

Pod not produced                                            Pod 12-25 cm long, 2-2.5 cm thick       Pod 15-25 cm long, 1.5-2 cm thick


I think there should be no doubt about both sets of plants (uploaded by … and …). Both belong to B. x blakeana. Agreed that sometimes the flower colour in B. purpurea may look similar, but that species has three stamens, and petals are much narrower. B. variegata has broader petals and five stamens, all nearly of the same length. B. x blakeana also has five stamens, of which three are longer and two shorter. This characteristic feature can be seen in both sets of photographs.


I think Hongkong orchid but not sure about sterile hybrid though many plants have sterile hybrids

Yes B. x blakeana, 3 long stamens and two short stamens.


This is B. purpurea. (Photo should probably be renamed to avoid confusion with B. x blakeana of same photo name).


… agreeing with Ken on this Bauhonia veriagata5A.JPG being Bauhinia purpurea.


Enlarged central portion of Bauhonia variegata5A.jpg to clearly show three long and two short stamens, characteristic of B. x blakeana


… had also mentioned a difference in the cut section of the buds; triangular in one and circular in the other.



The problem in raising this tree (Bauhinia X Blakeana)  is that one is not sure whether or not it is the same variety. Nurseries often palm off variegaata or acuminata in its place. Anyway now I have it. The other challenge is to convert this bushy tree into a shapely one!


Another special point I forgot to mention last time is that this flower was discovered in Hongkong and as it is a cross, only vegetative propagation is possible. So like Bodhi Vriksha all the trees have been developed from a single plant. This is the national (!) flower of Hongkong.


If I was allowed to nominate two Flower pictures of the year, this one would have been my second one. I had posted this plant from Herbal Garden plant, and simply love it for its beauty and unique story of origin. Here is link to my upload

 



This has bloomed in my garden for the first time. Grateful for  detailed ID. Is it variegata or blakeana?


… most probably the Blake’s bauhiniaBauhinia x blakeana … the official floral emblem of Hong Kong.

Please wait for comments.


I agree with …


Thank you … You know first time the nursery sold me a couple of plants of B. acuminata. The second time from another nursery I got B. variegata in the name of B.X Blakeana. This is the third trial. Did they say ‘Third time Lucky’!


Continuing with the series on flowering trees, this one was taken 10 days back at Sunder nursery (Delhi) just 10 days back.

The flowers looked  much more beautiful than what the photo could capture.


I think this is Kachnar (Bauhinia variegata) with five long stamens as in the picture compared to 3 long ones & two short ones of Hongkong Orchid Tree (Bauhinia blakeana). You may see the earlier thread of Kachnar on Indiantreepix (in which there was a lot of discussion) at.


I am in no way an expert in the field and therefore can be wrong in id
This shot was taken at tree walk led by Mr Pradeep Kishan and was ided as Bauhinia blakeana
Besides:
The flowers were pretty large and deep coloured
There seem to be 3 long and 2 short stamens (another pic attached)
No leaf shot could be taken(largely because of speed of the walk)

I leave it for the experts to comment further


I further think that it is a bit early for kachnar to flower in delhi


On further re-look at the picture, it seems you may be right.


It has rich Purplish red flowers & is the most beautiful among all Bauhinias. Often confusable with Kachnar. However, it has three large stamens (with two smaller ones) unlike five long stamens of Kachnar (Bauhinia variegate). Leaves are also not over-lapping near cleft unlike in Kachnar. It is sterile (does not produce seeds). All pictures taken on 27/1/07 at Garden Reach, Kolkata with the assistance of …

/wp-content/uploads/2020/10/Hoopoe%201.jpg

HOOPOE: Few years back I read a Middle in The Times of India, where the author was narrating his observation about a Woodpecker. From his description I could make out that he was talking about a Hoopoe. This mis conception about Hoopoe is not restricted to the city folks. I have asked about the identity of this bird from the villagers, they also think that the bird is Woodpecker. Attaching an image of this bird. I am also attaching an image of Bauhinia Purpurea (Deva Kanchan). Once in bloom. none can miss this tree.


– This appears  to be Bauhinia x blakeana to me. If I am not mistaken, I can see the characteristic black margins and centre spot black, on one of the petals in the top left flower.

Family: FABACEAE
One of the hybrids of Bauhinia. It is often called as Hong Kong orchid tree. It originated in Hong Kong in 1880 and apparently all of the cultivated trees derive from one cultivated at the Hong Kong Botanic Gardens.

look like Bauhinia purpurea


all pics says Bauhinia purpurea , but the close up flower pic resembles Bauhinia x blakeana .
As the close up pic z frm a similar tree I assumed it too as
Bauhinia purpurea. But may b dat z
Bauhinia x blakeana.


really no idea… cv are most difficult ones to id.


It is Bauhinina blakeana

Kindly see the differences I had listed with my upload of B. blakeana


This one is Bauhinia blakeana as it has 5 stamens.
Bauhinia purpurea has 3 stamens. Check my pictures posted today.
Agreed the overall look of B.blakeana is darker esp the the darkest petal

Fabaceae – Caesalpinioideae (Caesalpinaceae) – Bauhinia × blakeana S. T. Dunn from Hong Kong: Bauhinia × blakeana S. T. Dunn
Family: FABACEAE
One of the hybrids of Bauhinia. It is often called as Hong Kong orchid tree. It originated in Hong Kong in 1880 and apparently all of the cultivated trees derive from one Cultivated at the Hong Kong Botanic Gardens.

All Hong Kong cents have image of flower of this plant. I assume there are only two countries in the world who have hybrid flowers as their national flower, Singapore with Vanda Miss Joaquim and Hong Kong with Bauhinia blakeana.
History (WIKI): This tree was discovered in around 1880 near the ruins of a house on above the shore-line of western Hong Kong island near Pok Fu Lam and propagated to the formal botanical gardens in Victoria/ Central. It was later named for Sir Henry Blake, British Governor of Hong Kong, from 1898 to 1903 who was a keen amateur botanist, by the man who made the first thorough scientific description of the ‘Hong Kong orchid tree’ S. T. Dunn, Superintendent of the Botanical and Forestry Department, who assigned it to the genus Bauhinia and named it after Blake in his paper of 1908.

It is Bauhinia purpurea.


i guess B. blakeana and not B. purpurea


Considering the latest and earlier discussions on similar post by you I think this is B.blakeana as I can see 2 small stamens and some longer stamens ..total should be 5.

Pls ID. Bauhinia purpurea?
Place-Alapuzha
Habitat-cultivated garden.
Height-15 feet.erect tree.

Flowers-rose scented.

Bhauhinia racemosa


The images are of Bauhinia variegata L.


I think, you could also check for Bauhinia x blakeana….


Looks more like B. x blakeana

5 stamens are clearly seen, petals broader, so B. purpurea is out of race

Flowering season of 3, B. purpurea summers in Delhi, mostly July to October, B. blakeana November to February along with leaves, B. variegata January-March mostly start appearing before leaves.


Thanks … that is a very nice succinct differentiation.

Could the members of this esteemed group help ID this Kachnar species from the Sukhna lake promenade, Chandigarh. These trees were planted in the 1960s under the guidance of MS Randhawa, then Chief Commissioner, Chandigarh, and were the result of grafts not directly from seeds.
The Kachnar at Sukhna bloom in winters only. The flowers have five stamens. The leaf is about 15 cm across. Pics were taken today.
Is this Bauhinia blakeana or Bauhinia purpurea?

Not Bauhinia purpurea


It is Bauhinea blakei.

Trees of Lalbagh, Bangalore – Bauhinia x blakeana – Hong Kong Orchid Tree (Please Confirm):


Pl. check as this plant does not set seed being sterile.


It’s true that this tree is sterile but very rarely I have observed one or two fruit being produced.


Is this the same Bauhinia which has a name plate as ‘ Bauhinia krugii urban in Lalbagh I have posted earlier?

Kindly confirm.


Bauhinia krugii is a synonym of B. monandra.
Although the flowers look similar the leaves appear quite different. It is a distinct species from the one discussed here.


Thank you for your reply and feedback.
I think my pictures are also of the same tree in Lalbagh that is discussed here.

I will resurface my post for you to see.


Some relevant feedback from another thread:
“I too think the tree label is wrong as 3 long and 2 short stamens are clearly seen. All features point to B. x blakeana, but I think the pod shown by … in another thread needs to be closely checked. The pod does not look like any of the two parental species or other species of Bauhinia. It may well belong to another tree, or perhaps a climber.

Is that pinkish colour of the petioles and the pink tinge of the new leaf normally a feature of B.x blakeana?
I have never seen this.


This tree has been bothering us for a long time. Assuming that pod belongs to this tree only, we have to completely reject the possibility of B. x blakeana. (you will find a lot of reports of pods on the net, but all cases of misidentification). Let us see the alternatives keeping this table in mind.

http://www.amjbot.org/content/92/3/525/T2.large.jpg

B. purpurea has only 3 fertile stamens, petals (more so upper petal) are much narrower and quite separated. This should exclude this also.
While comparing this photograph with mine (of B. x blakeana) I was curious about the width of upper petal, more in above pplant. While checking stamens closely I noticed that of the five stamens (in above plant, mine, as well as below link of B. variegata), three of the stamens a slightly longer with thicker pinkish filaments, two slightly shorter with thinner whitish filaments. Also the width of petals (especially upper overlapped petal) leads me to suggest that this tree may a darker coloured form of B. variegata only

But then perhaps flowering period has also to be explored. In Delhi B. x blakeana flowers from middle of November to about middle of December, B. purpurea flowers in September-October and B. variegata in February-March. The pattern in above garden may be kept in mind.


I was wondering, if anybody anywhere hasn’t been studying bauhinia for indepth study, for genetic analysis etc? May be we can get an input from them??
May be this plant is indeed a cutting from B. x Blakeana but has asserted a slightly different genetic codes or have a local environ based change in its behavior expression …like reverting back to one of the parents’ character as in flower size, petal size etc?
intriguing case study


As far as I can understand, a hybrid between two different species at the same ploidy level as parents would be sterile. It may produce flowers but due to problems of pairing (it has one genome each from each parent) no proper gametes would be formed and hence no proper pod formation. The only way it could be a sexual fertile species is immediate duplication of chromosomes after hybridization as in wheat or Tragopogon kashmirianus (I had described in 1976). I have never heard about production of pods in this species of Bauhinia.


Lalbagh always have surprises, as I find something new every time I go there.

But I haven’t seen a Bauhinia Tree which doesn’t have pods.

Every one of them have pods and plenty of them.


I have been taking care of 5 Bauhinia x blakeana trees and watching them through all the seasons for the last 20 years.
They normally don’t produce any pods. Once only in all that time about 5 years ago I did see one of the trees with 2 or 3 seed pods.
Sometimes nature surprises us all.


This is what I was getting at perahps…
intriguing and worth noting… and may be worth checking its ploidy?


To me it defies scientific logic to find mature fruits on B. x blakeana. It would be worthwhile to check whether this is really B. x blakeana. I am reproducing the key given earlier in another thread.


I fully agree with … and compliment his great efforts in providing detailed info. with keys etc.not only for this plant but also for all the postings whenever such doubts arise. Oh! it is great.


Plants and trees mutate like crazy, just like tumors is the lesson here, and they surprise the heck out of the experts, just when one thinks one has a handle on some damn tumor, something new turns up…
same story operates here I guess.

Bauhinia krugii Urban : ID Confirmation : Lalbagh,Bangalore : 020812 : AK-1: Pictures taken in Lalbagh,Bangalore on 24/7/12.

Flower dark purple in color.

Sorry for the bad quality pictures due to cloudy weather.

Kindly validate.


For me the ID on the name board seems to be correct. It is Bauhinia monandra. Bauhinia krugii is the synonym of Bauhinia monandra


Resurfacing my post as the tree under discussion seems to be the same.


… to me this flower looks very much like the Hong Kong orchid, Bauhinia blakeana.

Have not yet seen Bauhinia monandra – the name suggests Bauhinia bearing one stamen … though not sure monandra in this context implies one fertile and some infertile.

good description here.


I agree the flower looks like B. x blakeana, but I have never seen leaves like those in the pictures on that species. That pinkish tinge and the way the new leaves are folded is not seen in B x blakeana. That tree’s new foliage is always a lightish green. Veins also look more prominent in your pics. IT is not easy to make a definite judgement based only on these images.


I think there should be little difficulty in getting correct identity if … remembers major aspects of the plant. Leaves are very small in B. krugii

Bauhinia monandra (syn: B. krugii)             Bauhinia x blakeana
1. Leaves 2.5-4 cm long.                           1. Leaves 9-13 cm long
2. Flowers in a short raceme.                     2. Flowers in a large panicle
3. Fertile stamen 1.                                   3. Fertile stamens 5, 3 longer.
4. Pod formed.                                          4. No pod formed
5. Flowers pink with purple veins.             5. Flowers with purplish petals.

6. Petals barely 3 cm long.                        6. Petals 5-8 cm long.


Thanks … i for the summary.
The ones in Lalbagh have lots of pods.
Atleast I know two of them one near the rose garden, another near the palms
I have the pictures of both of the trees in this link. I have also uploaded in the group

Thanks a lot for the distinguishing features between the two.

Both the set of pictures posted by … are of the same tree photographed by me.
This is near the palms, a small tree with two main trunks.
Leaves are definitely not small, but large.
Flowers very dark with purple petals.
Only confusing factor is the pods. Although I haven’t seen any, … photographs have pod formation.
You can see the pinkish tinge on the new leaves.
Even … has posted the same flower earlier.

Although the flowering season was over when I took the pictures, the single dark flower caught my attention. Had not come across a Bauhinia so dark pink, almost purple.


If the tree really bears mature pods, it can’t be B. x blakeana, which being a hybrid does not set seeds/pods,

One has to check the number of fertile stamens and leaf size to confirm.


I don’t think it is B.monandra as B. monandra clearly has only one big single visible stamen. Others may be small or rudimentary. Here I can see many and all appear equal in size.


I too think the tree label is wrong as 3 long and 2 short stamens are clearly seen. All features point to B. x blakeana, but I think the pod shown by … in another thread needs to be closely checked. The pod does not look like any of the two parental species or other species of Bauhinia. It may well belong to another tree, or perhaps a climber.


If this tree is same as one uploaded by …, then perhaps comments in the other thread have to be kept in mind.


Taking it as Bauhinia variegata as per another thread

It will be Bauhinia blakeana as per keys at HYBRID ORIGIN OF BAUHINIA BLAKEANA (pdf)


Thanks for the update.

Many of us had thought it to be Bauhinia blakeana earlier.


…, the label is misapplied. B. kurgii is now considered as synonym of B. monandra which has flowers with marrower pink petals, only one posterior petal is red and most important has only 1 fertile stamen.

But it does not look like B. x blakeana also as there are only three well developed stamens, other two seem much smaller. Most important leaves don’t seem lobed (1/3 to 1/2 in purpurea; 1/4 to 1/3 in blakeana and variegata)


Pl. check.


Yes … It is the same tree.


I can add a close up of the flower if required.


Better a view of leaf showing leaf apex.


I could find these pictures.
Hope they are of help.

I think yes B. x blakeana, leaf parted 1/3.

Bauhinia purpurea or Bauhinia blakeana ? Mândû, Madhya Pradesh, 600m, january 2020.

Cultivar ?


Another image.


Finally, i choose B.purpurea compared to flowering in winter, but few things separate them…


Can you send a close up of the flowers clearly showing the arrangement of stamens to Id the plant. Also refer to Trees of Delhi by …, wherein the proper key is available.


OK, according to the book “Trees & shrubs of India” P.Sachdeva and V.Tongbram, B.blakeana is an hybrid of B.purpurea and B.variegata.
